Abstract
An aircraft dynamics refined in aerodynamics is unstable and then such an aircraft is normally stabilized by automatic flight control systems. The pilot's control system for the aircraft with automatic flight control has two method. One is pitch command/attitude hold system which gives pitch attitude response to control stick deflection. Another is rate command/attitude hold system for pitch rate response to control stick deflection. In this paper, handling qualities to the two pilot's control methods are discussed experimentally using a fixed base simulator. The results are shown that the handling qualities of the aircraft with the rate command control system are inferior to that of the attitude command control system, but the qualities of rate command control system can be improved by the addition of the shaping filtere.
